*Additional Information: This head accepts factory rocker arm rails, we highly recommend getting a trunnion upgrade kit if your reusing stock rocker arms or aftermarket roller rocker set like Yella Terra, Scorpion or Harland Sharp. Without doing these upgrades you will experience accelerated valve guide wear.
